I recently bought a restored AC Delco cassette / radio which had been updated/ repaired with some new capacitors.

On my old one, I had an aux cable added to it which I was able to run Bluetooth from using a device from Amazon. The problem with that was having to charge up the aux/ BlueTooth device and so with the replacement I had the option of the seller to add a JC-Audio DAC305 internally in the stereo.

After waiting weeks and getting hit badly by customs, it arrived yesterday. I fitted it and tried the tape player first which was perfect. Then connected to Bluetooth- with ignition on but no engine running I get a really annoying high pitched buzzing.

Fine with tape/ terrible with the Bluetooth. It was fine using Bluetooth before when it was the aux arrangement.

Sending it back to the builder in thee States would cost an arm and leg so wondered what my options are- would something like this work? https://www.amazon.co.uk/Isolator-Suppressor-Ampli...

Thanks

Meant to say that this buzzing is just with ignition on- not with engine running.

Yes definitely correct part- separating the power supply- not sure I have the skills for that.
